摘要

VA Tech的OLYMPUS传播实验包括12 GHz、20 GHz和30 GHz信标接收器，仰角为14度，提供了有价值的多频闪烁数据。根据塔塔斯基(1961)的弱涨落理论推导了闪烁强度的频率标度规律，并与实验结果进行了比较。对几个闪烁事件的分析表明，对于较大的闪烁，该理论可以很好地预测闪烁强度的标度比。对于小的闪烁，有必要考虑热噪声的影响

Preliminary results on scintillation intensity frequency scaling from the Virginia Tech OLYMPUS experiment

The VA Tech OLYMPUS propagation experiment, which includes 12, 20, and 30 GHz beacon receivers at an elevation angle of 14 degrees , provides valuable multifrequency scintillation data. The frequency scaling law, of the scintillation intensity derived from V.I. Tatarski's (1961) weak fluctuation theory is compared to experimental results. An analysis of a few scintillation events indicates that for large scintillations the scaling ratios of the scintillation intensity are well predicted by the theory. For small scintillations it is necessary to take the effects of the thermal noise into account.<>
